About this item

The SparkFun Capacitive Touch Breakout Board (SEN-12041) is a compact module featuring the AT42QT1010 capacitive touch sensor. This single-button sensor detects touch via a conductive pad and outputs a digital HIGH signal when activated. It operates on a supply voltage ranging from 1.8V to 5V and includes an onboard LED that lights up upon touch, which can be independently controlled by modifying a jumper. Additionally, a PAD pin is available for connecting an external electrode, allowing for customization of the touch interface. The board is ideal for integrating touch functionality into projects without mechanical buttons.
